Title: FIBER TREATING AGENT FOR WATER ABSORBENT ARTICLE, FIBER, NONWOVEN FABRIC AND WATER ABSORBENT ARTICLE
Abstract:
The purpose of the present invention is to provide a fiber treating agent for a water absorbent article, which is capable of imparting liquid return-preventing properties to a water absorbent article such as a paper diaper or a sanitary napkin while allowing the water absorbent article to maintain the original water permeability and allowing the surface material thereof to show a weakly acidic pH, and which is hardly washed away by fluids such as urine or sweat and repeatedly ensures water permeability. The fiber treating agent (D) for a water absorbent article according to the present invention comprises fatty acids (A) containing 45-95 wt% of oleic acid derived from a natural fat or oil, a polyoxyalkylene adduct (B) of a natural fat or oil, and a fatty acid ester (C) of a polyoxyalkylene adduct of a natural fat or oil, characterized in that: the content of the fatty acids (A) is 0.3-3.0 wt% relative to the total weight of (A), (B) and (C); and an aqueous solution, which is prepared by diluting the fiber treating agent (D) with water in such a manner as to adjust the total content of (A), (B) and (C) to 1 wt%, has a pH value of 4.5-6.5.
